A power tool, in particular a hand-held power tool, includes a tool-holding device that rotates about an output axis. The tool-holding device is configured to hold a tool device on the power tool such that the output axis and a tool rotation axis substantially coincide. The tool-holding device has at least a driver device and a clamping device that is movable relative to the driver device. To transfer a driving force to the tool device, the driver device has at least one torque transfer region that is arranged at a distance from the output axis. The driver device and the clamping device are configured to reach through a cut-out of the tool device, which cut-out extends through the entire material thickness of the tool device, and to clamp the tool device via the clamping device, which is movable substantially in a direction radial to the output axis.
